      Proper Problem Reporting for the TFDi Design 717   07/09/2017

      Folks, As the user count is increasing, it is becoming more of a task for us to stay on top of problem reports. We are also receiving an increasing amount of incomplete reports that we are unable to follow up on (which frustrates everyone, us included). On that note, we are going to be enforcing a stricter formal problem reporting system. There are a few main points that need to be addressed. ALL problem reports must be submitted via the Bugs and Suggestions system. Open discussion on the forums is fine, but our team simply cannot respond to every single comment (especially when the majority of doing so is asking for information the Bugs and Suggestions system already asks for). Incomplete reports will be ignored. This means reports like "my FPS is bad" will not be given weight. This isn't because we don't care. It is because a report like that does absolutely nothing for anyone - we can't fix it based on that. Please include EVERYTHING you can possibly think of regarding the problem and take as many steps as you can to isolate it. Prepar3D v4, despite what you have heard, can still be unstable. Yes, it is definitely possible to fly flights without issues. But it is still relatively new, as are most of the addons available for it. Please refrain from attacking us or other developers because of this. We have already had one scenario where a 717 CTD was resolved by an update to Prepar3D itself. This is likely not the only time that will be the case. You are still free to report the crashes, as it may help whoever the developers of the faulting code are solve the issue. Duplicate reports will be deleted/merged. For the sake of sanity for us trying to prioritize and evaluate issues, if we discover multiple reports of the same thing, we may merge/delete the duplicates. We strongly encourage you to search and see if your problem has been reported before. Thank you all in advance. This may seem overbearing, but this is the only way we are going to be able to stay on top and continue heading in the direction we, and the community, want.

717 Throttles stopped responding

Recommended Posts

I had the same experience of none responsive throttles, everything was running on the aircraft, flight controls all worked fine but no throttles, even though engines running fine. I was at FL30 so had plenty of time to work the issue. The only thing I had done different to any other flight was to open up the fsx map view, which I never normally use, when I closed it and returned to the flight no engine response. I eventually got over the issue by hitting CTRL+E and got immediate response again.

Not sure if that helps any, hope so.

@stretch1365 Did it begin IMMEDIATELY after opening the menu? We're going to add some extra debug information to the MCDU to help nail this down in the next update. It's odd, as it's not happening to everyone.

 

Edit: I just read what you said again and answered my own question. Does opening the map reliably recreate this issue?

I have had the same problem. Thought it was maybe fuel failing to load correctly from Addon Manager, but fuel panel showed over 4 tonnes in the two wings tanks when problem occurred. The first time it occurred I tried to re-start the engines but this did not work. Last night it happened again at FL290, rectified by switching off autopilot then setting both FADEC's to ALT. Dropped to FL130 by the time I got going again, was able then to go into autopilot mode  (Nav, Speed and Path) and complete my flight without further incident.

Just read another post on this - I too had opened MAP view (FSX style) on both occasions when this happened.

Same here. Happened on ILS approach (autoland engaged) to KPIT 28R. The throttles wouldn't engage even in stall protection and ALT FADEC brought back the engines. I had paused the sim and the unpaused it and that's when it started to act up.

After dozens of flights I had it happen to me last night. Halfway through the flight I noticed I was slowing down. Throttles were full. Disengaged the autothrottle and tried the throttles manually and nothing happened. Engines stayed idle but the throttles are clearly moving.

Likewise here.  Throttles died 30 minutes into the flight.  Lo speed thrust came on and it fell out of the sky.  Couldn't do anything about it. Back into the hangar for this birdy :(

FADEC to ALT on the overhead, wait for the spool and FADEC to normal. It will work.

Now I've joined the Club.  On final after a long flight from Perth Aust to Port Hedland a mining town, I got to begin the approach without a CTD (stayed in VC mode all flight), when the same thing happened.  It is uncanny, the hardware throttle works apparently, so do the F keys, but the engines have a mind of their own.  In my case speed would not come down to below 250, the landing overshot and the plane after scrub bashing for half a mile took off in a go round.  So I did a circuit and replicated the exactly same behaviour.

I have just replicated the YPPH-YPPD flight of 863nm.  I used a SID on departure and an RNAV approach for landing at a non-ILS airport.

I stayed in VC Mode all the way, no view switching so no CTD. Did not speed up the sim either.

Unlike the previous day, I used autoflight descent not PROF, and did not use the Appr/Landing that I did the day before. I have my suspicions that the auto-approach facility gets lost on RNAV arrivals. This could be the key.

Autoflight hit all descent altitudes and speeds.  Brought hardware throttle back to approx match the pedestal positions. (This may have been important).

Did a full flap manual landing on an 8700ft runway with room to spare after using reverse and spoilers (automatic).

EPR and N1 settings appeared normal at all times.

You may not be able to make head nor tail of  this, but it would seem that alternate techniques can be used.

Its only happened to me once and that was at cruise. Not during decent or approach. Have flown at least a dozen more times without the problem. Bizarre

I'm still having trouble with the throttles in flight. They just stop responding while in flight and I basically have to shut the sim down. Annoying is an understatement😃. Hope a fix comes soon because I got the plane in the hanger until a fix comes.

I was simply cruising on AP without a flight plan. I inspected the sim's Fuel and Payload menu (no changes made).  When I closed it, the engines immediately started spoiling down. The FADEC technique saved the flight. Subsequent attempts to reproduce the problem didn't result in a failure.

I have just had the same problem.  Mid cruise - no map views or view changing - and I heard the stall warning while n the other room.  Engines at idle and not responding to throttle input.  The FADEC trick worked - I got control of the engines back and re-engaged AFS to bring aircraft back on course.  It's the first time it happened.

(edit)

Then it happened again - immediately after looking at map view 🤔

We will be continuing to investigate this - it seems to have stopped in our internal builds.
